MAINS PRESSURE
The water heater is designed for direct connection to the mains water supply. If the mains supply pressure in
your area exceeds that
should be greater than 140 kPa for the rated flow and performance to be achieved.
HOW HOT SHOULD THE WATER BE?
The water heater may be installed with one or more user
adjustable temperature controllers, which allow you to choose
the most suitable temperature for your hot water needs (refer
to
"Temperature

If a controller is not installed, the water heater heats the water
to the preset outlet temperature setting. The factory preset

heater cannot be adjusted by the householder. The setting
can only be adjusted by the installer, your nearest Rheem

system, the installer has checked and if required, adjusted
the preset outlet temperature setting of an 864 series water
heater to 55°C.
Warning: Temperature controllers must not be fitted to
this water heater (864 series) as part of a solar water heater system installation because water at a
temperature much higher than the controller setting can be delivered. If a solar preheater has been installed
to an existing water heater installation, then all controllers must be disconnected and removed.
If this water heater is installed as part of a solar water heater system, the system can deliver water at
temperatures from 58°C up to 75°C and possibly higher depending upon the model of solar water heater
installed.
HOTTER WATER INCREASES THE RISK OF SCALD INJURY
This water heater can deliver water at temperatures which can cause scalding. Check the water temperature
before use, such as when entering a shower or filling a bath or basin, to ensure it is suitable for the
application and will not cause scald injury.
